![]() Multiple versions of DisplayPort have been introduced. There are two connector types for DisplayPort: DisplayPort and Mini-DisplayPort. The standard replaces other standards such as VGA, DVI, and HDMI, but allows for adaption to older video standards. DSC bitstream support can reduce DisplayPort transport bandwidth in excess of 67 percent without visual artifacts, while VESA’s Panel Replay capability can reduce DisplayPort tunneling packet transport bandwidth in excess of 99 percent when Panel Replay operation is taking place.DisplayPort is a modern digital video standard that is typically used for computer monitors. This increased efficiency is on top of mandated support for VESA’s visually lossless Display Stream Compression (DSC) codec and VESA’s Panel Replay capability. In addition, DisplayPort 2.1 has added a new DisplayPort bandwidth management feature to enable DisplayPort tunneling to coexist with other I/O data traffic more efficiently over the USB4 link. As such, DisplayPort 2.1 has tightened its alignment with the USB Type-C specification as well as the USB4 PHY specification to facilitate a common PHY servicing both DisplayPort and USB4. All of these changes have been made to accomodate the current pin layout and physical dimension of both these connectors.Īchieving a robust, end-to-end user visual experience remains the utmost priority for VESA’s DisplayPort specification, whether across a native DisplayPort cable, via DisplayPort Alt Mode (DisplayPort over the USB Type-C connector), or tunneled through the USB4 link. VESA certified DP40 cables support up to the UHBR10 link rate (10 Gbps), with four lanes, providing a maximum throughput of 40 Gbps, while VESA certified DP80 cables support up to the UHBR20 link rate (20 Gbps), with four lanes, providing a maximum throughput of 80 Gbps.ĭue to the higher speed(read frequencies), the physical layout of the DisplayPort connectors(both MiniDP and DP) had to be adjusted in order to prevent crosstalk and jitter. ![]() ![]() DisplayPort 2.1 has also updated the DisplayPort cable specification to provide greater robustness and enhancements to full-size and Mini DisplayPort cable configurations that enable improved connectivity and longer cable lengths (beyond two meters for DP40 cables and beyond one meter for DP80 cables) without diminishing UHBR performance. The major change in v2.1 is to have a better understanding of the 2 different speeds supported, DP40 and DP80. With the release of DisplayPort Alt Mode 2.0, all of these high-performance video capabilities are now available to the USB ecosystem. Featuring the highly efficient 128b/132b channel coding shared with USB4, DisplayPort 2.0 delivers a maximum payload of 77.37 Gbps across four lanes (up to 19.34 Gbps per lane)-supporting ultra-high display performance configurations such as an 8K (7680×4320) display with 60Hz refresh rate with full-color 30 bpp 4:4:4 HDR resolution uncompressed, and 16K (15360×8640) 60Hz display with 30 bpp 4:4:4 HDR resolution with compression. ![]() These include beyond-8K resolutions, higher refresh rates and high dynamic range (HDR) support at higher resolutions, improved support for multiple display configurations, as well as improved user experience with augmented/virtual (AR/VR) displays, including support for 4K-and-beyond VR resolutions. DisplayPort 2.0, which was introduced in June 2019, provides up to a 3X increase in data bandwidth performance compared to the previous version of DisplayPort, as well as new capabilities to address future performance requirements of displays. ![]()
